I liked Jessamyn's post about the high cost of everything. Databases are expensive, and intangible, which makes it trickier to justify them. But librarians are often challenged to justify our existence in general, and the burden is usually on us to convey to the public how valuable libraries are.

This talk about how much things cost reminded me of the Library Use Value Calculator. This tool lets patrons enter their library usage (how many books they check out, how many reference questions they ask, etc), and see a dollar figure of how much their library usage would cost them if they had to pay for it "retail."

They did, and since then it has spread. Here's a list of library websites that either feature or link to the calculator (if I missed you, please include a link to your library in the comment section). Below that are a few other blogs and websites that mention the calculator, including Library Journal and PLA.

If you're a librarian and looking for a tool to justify your existence, this might be a way to give people actual numbers. Feel free to modify and reuse the calculator code yourself, and let me know if I can help - bherzog@mvlc.org.
